Abstract
The utility model relates to a profiling mold mechanism which comprises the traditional profiling mold mechanism body and an inside profiling mold. The profiling mold is combined with the profiling mold mechanism in the traditional manner. The profiling mold mechanism further comprises an electric heating device and a thermostatic control device, wherein the electric heating device is positioned inside the profiling mold and has a shape identical or similar to that of the profiling mold, and the thermostatic control device can control the temperature to be thermostatic in a certain range; an insulating heat conduction layer is arranged between the electric heating device and the profiling mold; the thermostatic control device is electrically connected with the electric heating device; and the profiling mold, the insulating heat conduction layer and the electric heating device are closely combined.
Description
Technical field
The utility model belongs to the precision-investment casting field, refers in particular to a kind of casted die mould mechanism that is used for fusible pattern injection.
Background technology
" lost-wax casting " claimed in model casting again; Typically refer to fusible material and process apperance, coat the several layers refractory material on the apperance surface and process shell, again shell is discharged in the apperance fusing; Thereby obtain the casting mold of no die joint, after high-temperature roasting, get final product the founding method of back-up sand cast.Because apperance extensively adopts wax material manufacturing, so often model casting is called " lost-wax casting.
First operation that precision-investment casting is produced is made fusible pattern exactly; Fusible pattern is the model that is used for forming the medium-sized chamber of fire-resistant shell; So obtain the high foundry goods of dimensional accuracy and surface smoothness, at first fusible pattern itself just should have high dimensional accuracy and surface smoothness.It is simple that the performance of fusible pattern itself also should make operations such as system shell subsequently as far as possible in addition.For obtaining the fusible pattern of above-mentioned high-quality requirement, except good die mould (mould of fusible pattern injection) should be arranged, also must select suitable pattern-making material (being called for short the mould material).
When using cerul mould material, the mould material of gained can reclaim after the demoulding, is used for making new fusible pattern again.When recycling, the performance of mould material can degenerate, and fragility increases, and ash content increases, mobile decline, shrinkage factor increases, color is brown by leucismus, in these main and mould material stearic go bad relevant.Therefore, in order to recover original performance of old mould material as much as possible, will from old mould material, remove soap salt, method commonly used has hydrochloric acid (sulfuric acid) facture, atlapulgite facture and electrolytic recovery method.
Simultaneously, in compacting during pattern,, generally be that softening or materials such as liquid such as paraffin are joined in the tamping mechanism,, treat again pattern to be taken off from tamping mechanism after these material cooled sclerosis with expendable pattern material compression moulding with pressure or other method.In the traditional handicraft, for the ease of pattern is separated from tamping mechanism, during compacting cerul mould material, parting compound can be machine oil, turpentine wet goods; During compacting resin basic mode material, the mixed liquor or the silicone oil of sesame oil commonly used and alcohol are made parting compound.This this parting compound is applied to earlier on the tamping mechanism, again progressive type mold pressing system.
Expendable pattern material can repeatedly reuse; After using parting compound, expendable pattern material is when fusing, and the parting compound that is applied on the tamping mechanism also carries out in the expendable pattern material thereupon; This result is exactly the very fast blackening of color of expendable pattern material, and the number of times that recycles of these expendable pattern materials is reduced.Simultaneously, these parting compounds also can carry out in the environment and cause environmental pollution when melting, even handle, also can increase production cost.
Seek a kind of can be free from environmental pollution, color that simultaneously also can expendable pattern material, the technology that improves expendable pattern material recycling number of times is the object of the invention.
The utility model content
The purpose of the utility model is to improve the recycling number of times of expendable pattern material, and guarantees color and luster and reduce environmental pollution.
The utility model is realized through following technical scheme:
A kind of casted die mould mechanism; Include traditional casted die mould mechanism body, gland and inner casted die mould; Said casted die mould comprises external mold and internal mold; Casted die mould engages with casted die mould mechanism body in a conventional manner, also comprises being positioned at the internal mold interior shape with the same or analogous electric calorifie installation of casted die mould and can control the thermostatically-controlled equipment of temperature constant in certain limit, and described electric calorifie installation is with an insulating heat-conductive layer is arranged between the casted die mould; Described thermostatically-controlled equipment with between the electric calorifie installation by electrical connection, described casted die mould, insulating heat-conductive layer and electric calorifie installation are combined closely.
In this patent, the temperature controlling range of said constant-temperature temperature-control device is 45-55 ℃.
This patent is with the prior art following advantage of having compared:
In this patent, do not re-use parting compound, in paraffin, just no longer include dissolving in of parting compound like this, thereby guaranteed the purity of paraffin, and can not make the blackening of paraffin color yet, increased the number of times of recycling.Technology through this patent makes wax-pattern with separating in the tamping mechanism, when wax-pattern near the tamping mechanism position, because of under the situation of deliquescing, separating; The certain friction and Extrusion that produces; Make mold inner surfaces more smooth, improved product and casting accuracy, some product can reach directly satisfies the demand and need not be again handles through shaping; Improve speed of production and also reduced operation, reduced production cost.

The specific embodiment
Be elaborated in conjunction with the technical scheme of accompanying drawing to this patent.
Contrast illustrated in figures 1 and 2ly, a kind of casted die mould mechanism includes traditional casted die mould mechanism body 2, gland 1 and inner casted die mould, and described casted die mould comprises external mold 5 and internal mold 3; Casted die mould engages with casted die mould mechanism body 2 in a conventional manner; Also include and be arranged in internal mold 3 interior shapes with the same or analogous electric calorifie installation 4 of casted die mould and can control the thermostatically-controlled equipment (in legend do not illustrate) of temperature constant in certain limit; Described electric calorifie installation 4 is with an insulating heat-conductive layer 6 is arranged between the casted die mould; Described thermostatically-controlled equipment with between the electric calorifie installation by electrical connection, described internal mold, insulating heat-conductive layer and electric calorifie installation are combined closely.
In this patent, the temperature controlling range of said constant-temperature temperature-control device is 45-55 ℃.
When work; Pour in the casted die mould after the wax fusing, suppress, treat to restart after the wax-pattern cooling hardening electric calorifie installation of this mechanism through pressure; Control temperature range between 45-55 ℃ through thermostatically-controlled equipment; Physical property according to paraffin is same, near the slightly deliquescing of electric calorifie installation paraffin partly, at this moment just is easy to wax-pattern is separated from casted die mould.
This specific embodiment just is used for explaining this patent rather than to the restriction of this patent protection domain.Arbitrary those skilled in the art all understands, and the change through the technology to this patent adapts can realize the object of the invention fully, and this all changes is the protection domain of this patent.
